Been a lurker all the 'while' ... learning. :-)
I have a good friend who owns a 94 Alfa 164 V6 with per plug , individual spark coils ... coil_s_ on '6'.
'She' needs at least one(1) replacement coil . Replacement 'coils' are hen's teeth ... too expensive, even if found ... $150USD each.
Now the question ...
Is there a 'way' to determine *if* another Margue's plug_coils will function electrically ? Toyota ... Camry V6 , Avalon V6/8 Audi ...
I suspect 'so', but dont really know. The problem of mechanical mounting can be overcome ... will_power and BIG 24 oz hammer_tures.
*If* the "?alt_equivalent_part?" prim/sec coil resistances were in the ball park , and the "Igniter" feed voltage to the coil(s) was 12vdc ... mite "that" be an indictor of substitution_ability ???
I'm reasonably sure that the Toy Camry V6 per_plug_coils are 12vdc 'feed' all 6 coils feed from a =single= "Igniter" module for both V6 cyl banks ... no idea whats "in" the module.
The Alfa I'm not so sure ... I suspect 12vdc 'feed' tho. Added that there are two(2) "Igniter" modules , one per bank on the '164' V6. I dont even wannna =guess= at thier replacement cost . Then too, theres an 'ECU' under the dash ... ;_(
I'd be extremely appreciative of =any= advisories ... pointers ... as to "how" to look for the 'coil' substitutes.
BTW ... The '164' is an over_apholstered, speedy, 4 dr Italian "family" sedan , Dealerships long "gone' from USA environs .
